SPECIFICATION forming part of Letters PateintNo. 756,093, dated March29, 1904. Application filed lpril 20, 1903. Serial No. 153,533- (Nomodel.)

To all whom it may concern:

Be it known that we, JOHN BEETON and JAMES WARDALL, subjects of the Kingof Great Britain and Ireland,residingat HucknallTorkard, in the countyof Nottingham, England, have invented a new and useful File or Carrierfor Miners Pick-Blades and Like Tools, of

means have been used for distinguishing at a glance the set ofpick-blades belonging to one miner from those belonging to anotherminer. Now according to this invention we obviate these disadvantages bythe improved means about to be described.

To this end the file consists of a body portion having at one end ahandle and at the other end a base-plate, the said body portion beingprovided with a suitable number of vertical barssay threebetween whichtwo apertures are constituted. At the upper end of each aperture thereis a gap into which the pick-blades are introduced and are caused bytheir usual recess to engage with the inner face of the outer bars, whenthey can be slid down, the lowermost blade resting on the base-plate.Means are also provided for locking the blades to the file.

In the drawings, Figure 1 is a perspective View of a file constructedaccording to the invention and adapted for miners pick-blades,

and Fig. 2 is atransverse section of the same ured at its usual recess.At the upper part of said apertures there is formed in the body a gape,which is a little larger than the blade at its thickest part, so thatsaid blade can be introduced into said gap.

The side 6 of the outer bars a a is formed with a tenon or dovetail I)and is adapted to fit the usual recess in the pick-blade. The centralbar a may be of rectangular or prismatic section, or it may haveV-shaped edges a, as shown in Fig. 2.

At the lower end of the body a is the baseplate 6, and at the upper endis thehandle (Z.

A suitable mark, sign, or symbol may be stamped or cast on the handle orother part of the file, so as to readily cause one file to bedistinguished from another.

The handle (Z and base-plate 6 may be formed integrally with the body aby casting or otherwise.

. To insert or file a blade, it is introduced into the gap a and itsrecess caused to engage with the tenoned or dovetail side 6 of one of pthe outer bars, when it can then be slid down until it comes to rest onthe base -plate 6. Other blades can be inserted in a similar manner, buteach then resting on the one be-, low, and thus forming a pile. If thecentral bar a has .its edges V-shaped, a correspondingly-shaped grooveis formed in the blade, so as to engage one of said edges. This meansfor securing the blade to the file may be additional to the means abovedescribed and would be of especial use for securing blades or othertools that may have no recess.

To look the blades on the file, a padlock g (or other suitable fasteningdevice) is attached by its bow to the central bar a, so that when theuppermost blade is raised it carries the padlock with it until saidpadlock contacts with the top of the gap a", and thus prevents the bladefrom being removed from the file.

Having now described our invention, what we claim, and desire to secureby Letters Patent, is

1. A file or carrier for miners pick-blades (and other like tools)consisting of a body provided at one end witha handle and at the otherend with a base-plate, the said body being formed with tenons ordovetails down and into which the pick-blades (having the usual recess)are adapted to slide and engage, and means for locking the said bladesin place, substantially as described.

2. A file or carrier for miners pick-blades (and other like tools)consisting of a body term'inatingat its upper end in a handle and at itslower end in a base-plate and formed with vertical bars (a central andtwo outer ones) having slots or apertures between them, the inner faceof the outer bars being formed with tenons into which the pick-bladehaving a'recess is adapted to engage while the base of said blade restsagainst the central bar, a gap at the upper end of each of the slots orapertures to permit the introduction of the blades, and a padlock forlocking the blades in place, substantially as described.

3. A file of the character described, comprising a central bar and aside bar arranged on each side of said central bar, whereby two separaterows of picks may be held by said file, one being arranged between eachof said side bars and said central bar.

4. A file of the character described, comprising a central bar and aside bar arranged on each side of said central bar, whereby two separaterows of picks may be held by said file, one being arranged between eachof said side bars and said central bar; and means for locking the picksin position.

In witness whereof we have hereunto signed our names in the presence oftwo subscribing witnesses.
